Tokay Gecko - they are beautiful, they change colors, they can jump and climb your walls and hide on your ceiling, they have razor sharp teeth and will bite a huge chunk out of your arm if you get near it. They chirp like birds when mating and growl like the girl from the movie "The Ring" when angry. Very difficult reptile to have as a pet but worth it if you like lizards. Make sure you get two so they chirp at each other. NOT FOR CHILDREN! RIP my little buddy =(
